domain of y=e^x

domain

y = e^{x}

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

- \frac{2 x}{( x + 1 ) ^{2} ( x - 1 ) ^{2}}

18 x^{4} - 108 x^{2}

- 6 x - 2 y = 7

f (x) = - 1

f (x) = \frac{x}{x ^{2} + 64}
